LAN speed problem WRT54G v5

Hi,
I have a speed problem using ONLY the LAN.
I've disabled the firewalls, antivirus and connected the line directly to the computer using PPPoE without any modems.
I've tested the line with a big download using torrents. My speed is at 5-6 Mbps.
If i connect using router (using DHCP, PPPoE protocol and even with port forwarding set) my speed goes down to 1.5-2 Mbps.
I have only 1 computer linked to the router, but the IP provided by ISP it's dynamic, so i'm using router only for UPnP. I tryied with port forwarding bypassing the UPnP and still dosen't work.
The firmware is the last i've downloaded from your site 1 week ago.
Any suggestions please ?

DI followed your instructions and did all that.
No change. Same speed
Is it possible for that to be the maximum hardware speed ?

  • Very Slow lan speed at WRT54G v8

    Hello folks,
    I'm very sorry to bring this issue to you, but I've checked all the information avaliable at the forum and was not able to solve my problem. Here it is:
    I have in my house total of 4 devices:
    2- PC (P4 2.0 Gh 1 gb RAM) running Windows XP SP2 (hereby Pc 1 & Pc 2)
    1- Notebooks (Core 2 Duo) running Windows vista (hereby Note 1 / 2 & 3)
    1- Playstation 3 (hereby PS3)
    Before I buying my Linksys router I used an Thomson Speedtouch Modem as router, and all conections were wired. I had no problem at all. Upnp at this modem worked very fine, and wired transfer files on my network worked very fine (transferences at 9 mega bytes per seccond)
    Now, I've changed my router to wireless WRT54G v8.
    PC 1 & PC 2 are using cables
    Note 1 and PS3 are using wireless conection
    The internet conection works very fine. I have an assymetric internet (very commom in brazil) and I get 400 kbytes per seccond downloads, which mets my desire (speed is ok)
    But I'm having a hard time with the wired conections...
    I'm using PC2 as a download center. So, I download everything using this PC 2 and then share through the other computers on my network.
    But, if I try to download things FROM PC 2 to PC 1 I get about 30 kbytes per seccond speed (previously it was 9 megabytes per seccond)
    If I try to download things FROM PC 1  to PC 2 I get 9 megabytes per seccond speed (which is fine)
    If I try do download things from PC 2 to Notebook 1 I get 1 megabyte per seccond speed
    If I try to download things from PC 1 to Notebook 1 I get 3 megabyte per seccond speed
    Since I havent changed the cables from the previous instalation, the only responsible for the problem, as far as I can see, is the WRT54G router.
    Things I've tryed so far
    - Configuring firewall for correct IP authorization
    - Changing MTU to 1400
    - Changing the network card speed to 100 mbs full duplex on both computers
    But the problem did not go away.
    I would be very happy if any of you could provide me ideas to solve my problem.
    Thanksa lot!

    Sorry to bump this article, but my problem is not solved...
    I've tryed several things, but the problem cannot be solved...
    One thing I could figure out is that I cannot ping the PC which sends files very slowly.
    This could indicate that the problem is firewall related, but, checking Norton configs, it seems that everything is OK. Even if I desable completely, the problem still occour... Windows firewall is also desabled...
    I'm considering the idea of removing Norton firewall completely, because I think is related to it.
    Any thoughts??
    I've also tryed:
    changing network cable
    changing network card
    and the problem still occour...
    Help??

  • WRT54gc speed problem

    hy. i've got more of a question than a problem to be honest. and i must also say i understand the technical terms in networking but i ain't that good and i'm sorry if i can't really make myself clear.
    until about 5 days ago my Internet Connection was made through a modem which was connected to the router thus having internet to 4 computers (2 LAN, 2 Wireless). during this time, my router was configured with Automatic DHCP (or something like that) and a MAC clone of my PC.during this time and after about 4 years of fidelity , my internet connection was of about 6MB => ~700kbs download.
    now, my ISP provider "upgraded" my  connection and have direct cable connection. anyway, i now have a user name & a password. i switched the connection type to PPoE but i did not change anything else. the other settings are the same: MAC clone, open ports,Wireless MAC filters.
    So here is my problem:
    -if my PC is directly connected to the internet, i can achieve an efective download speed of 10 MBs (100 Mb connection or something like that) and upload speed of 1,6 MBs (12 Mb connection)
    -if i connect through the router i can only achieve about 3 MBs download speed (only 2,5MB the other PC LAN connected -> weird i'd say).
    As far as i know, the router should allow speeds of 10 MBs for 1 PC if the other computers aren't connected or don't need internet at a given time.
    So i was wondering if this speed problem could be related to the fact that i still have the other settings (mostly the MAC clone of my PC; this is the only one i can think of that might create a problem) or it might just be hardware related (doesn't allow me better speeds or something).

    well, since yesterday, i've reseted the router and only added the user name & password provided by my ISP but still it doesn't work as it should.
    about my connection, as far as i can say, my contract with my ISP has been modified from the cable contract to a fiberlink contract, most likely the cheapest (they have 2 kinds of contracts). but even with this cheap-fiber contract, i still should have a total 10MBs download speed! yet, my exact connection is of about 3MBs DL speed total. i know this because i used for download 2 PCs and have 3MBs DL and 1,5MBs UP.
    anyway, if it help here is how i think my contract looks like:
    Maximum bandwidth in your town -> 50 Mb / s
    Maximum Internet bandwidth        -> 50 Mb / s
    Traffic with maximum bandwidth on internet -> unlimited
    is it possible that the router only uses the Internet bandwidth ??? if so, is it possible to configure it so it uses the other one too?
    or is it just hardware limitations ?

  • HOME LAN CONNECTION PROBLEM

    HOME LAN CONNECTION PROBLEM
    I set up a 2 unit home net with a Linksys WRT54G Router, One PC hardwired to Port 1 and a Notebook conected via the wireless port. Both PC are Pentium and WXPPRO.
    When I try to browse the local workgroup ("MICASA") I get the following error message: "You have no access to "WorkGroup". You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The server list for this workgroup is not accessible at this moment."
    Wireless has MAC filter enabled and security disabled
    I restricted DHCP adresses to only 2 => 192.168.1.100 and 192.168.1.101
    Win XP Pro Firewall is disabled in both PC
    I worked as ADMIN with proper password in both boxes. Full file security enabled.
    Shared both C disks with proper local and share permits.
    In registry both PCs have: HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Lsa/"restrictanonimous"=0
    I could see both PCs in "my network places" for a couple of days, with full and proper file sharing, and then both pc's dissapeared. Both PC's access internet properly.
    The obnoxious message listed at the beginning began appearing when I click "Workgroup" in "my network places". I tried everything, including unsetting and re-setting file sharing for C disks. Nothing happens.
    The W2K Resource Kit Browser Monitor reports no brouser on the LAN.
    I can ping one adress from the other and I can log onto the other box shares by typing the name in Windows Explorer (\\Pentium or \\PCdeLidia)
    Any clue will be welcome

    Thank you, timelord.
    I checked the Node setting (ipconfig /all) and it is "broadcast".
    So, I decided to start all over again.
    1) I un-shared all shares in both computers (The notebook and the desktop).
    2) I reset the linksys router and used the Linksys setup wizard to reconfigure it from 0 (cero) - dropped (disabled)  ALL security - Left only admin setup password - Changed the workgroup SSID from "MyHome" To "Home" - just to be sure.
    3) Run network setup wizard in desktop (WXP Pro). Sharing Printers and files enabled.
    4) Stopped and Disabled the WXP firewall in the Desktop (it was disabled, but the network wizard enables it and leaves it running)
    5) Rebooted the Desktop
    6) At this point, I finally could browse the local lan and see my desktop listed
      My Network Places / All the Net / Microsoft Windows Network / "Home" / "Pentium" (my desktop)
    7) Went over to the notebook and re-checked all file-sharing was off, then I erased the WI-FI profile in it (uses the Intel wizard), changed the workgroup name from "My Home" to "Home", Rebooted it and connected it to the Wi-Fi "Home" net that was detected. ALL security disabled, including WXP Firewall.
    8) Now, the whole net is visible from both PC's
      My Network Places / All the Net / Microsoft Windows Network / "Home" / "Pentium" (my desktop)
      My Network Places / All the Net / Microsoft Windows Network / "Home" / "PCdeLidia" (my wife's  notebook)
    9) I enabled a couple of shares in both machines and I could browse them and connect to them
    10) Finally, all goes to hell: I shut-off both PCs and the LinkSys router. Then I powered the linksys, and then the Desktop. The notebook still OFF. And Voilá, same awful post:
    "You have no access to "WorkGroup". You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions. The server list for this workgroup is not accessible at this moment."
    I'm not even able to see myself.
    One tip: I used the browser monitor from W2K. Before, I was able to see 3 (three) lines listed, no browser. Unfortunately, i did not write it down. Now I can see only the following 2 (two) lines:
    MiCasa \Device\NetBT_TCPIP_ {€ unknown  (Not an Euro sign, something like that)
    MiCasa \Device\NwlnkNb         unknown
    Now I have to quit, no more time, I'll continue later and keep you posted
    Thank you again

  • E4200V2 slow wired LAN speeds

    Set up my new E4200V2 last night, everything appeared to be working but while streaming videos over wired LAN I get short hiccups over wired. While streaming videos, a few second long pause is really, distracting, this is a deal breaker and my previous router (DIR-655) had no issue streaming any videos. The wiring has not changed, only the router.
    So onward to trying to lock down the problem.
    I set up a ping between two wired linux boxes, and get:
    64 bytes from 192.168.0.5: icmp_seq=65 ttl=64 time=0.184 ms
    64 bytes from 192.168.0.5: icmp_seq=66 ttl=64 time=0.180 ms
    64 bytes from 192.168.0.5: icmp_seq=67 ttl=64 time=0.566 ms
    64 bytes from 192.168.0.5: icmp_seq=67 ttl=64 time=10.52 ms
    Whoa, 10 ms over gigabit LAN. This is crazy, but doesn't tell us much. The 10 ms was one out of hundreds of pings, so its only intermittant. This might explain the hiccups, but this router doesn't appear to log anything, so its hard to say.
    Next was scp transfers, which never exceed 15MB/s, in either direction. For gigabit, wired LAN this is awful, with my previous DIR-655 I would get at the very least 40 MB/s, in all situations.
    Next up, iperf. I set up iperf on the two hosts, and iperf reports reasonable gigabit speeds
    3] local 192.168.0.5 port 48303 connected with 192.168.0.3 port 5001
    [ ID] Interval Transfer Bandwidth
    [ 3] 0.0-10.0 sec 1.10 GBytes 941 Mbits/sec
    and on the iperf server:
    4] 0.0-10.0 sec 1.10 GBytes 940 Mbits/sec
    I have tried the following solutions:
    Firmware: its the newest firmware, as of last night (Feb 14) 2.0.36 build 126507 2011-12-23 01:39  
    MTU - I adjusted this to 1400, 1492, 1450, set to auto, no difference
    QoS - I enabled this as someone reported QoS being off would throttle certain transfers, no difference
    I added both the MAC addresses of the two linux boxes as High Priority in QoS, no difference
    I'm running out of things to try. Tonight I am thinking of reverting to an old firmware, doing a hard reset and seeing if it persists, and if no ideas come up in this forum, it is getting returned, 15MB/s over gigabit lan is terribly broken.
    Any ideas?
    Xian

    Try these troubleshooting steps:
    A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)
    1] Open the software and go to the option which says "Router Settings"
    2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.
    3] Then click on security and disable the SPI firewall.
    B] If you haven't installed Cisco Connect then you can log on to the router's user interface using it's default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the username field blank. This will take you to the router's web interface and then follow steps as mentioned above to make the changes.
    Hope it will help you.
    Second, you can reduce the speed of the LAN card as well. 
    Here is the step:
    START--> right-click My Network Places and click Properties
    right-click on the device and click properties
    Click on the CONFIGURE button
    Select the ADVANCED tab and the settings you can alter are listed on the left.
    Try to make the LAN speed to manual speed.

  • WRP400 wan-lan speed

    Hi All!
    I have a problem with my WRP400 WAN-to-LAN speed no more than 48Mbit/s incoming and up to 42-45 MBit/s outgoing.
    My connection is 100/100 Mbit/s, Firmware 2.00.26 , OS Win 7 Ultimate.
    QoS disabled, VoIP not in use.
    Is there any possibility to increase speed?
    Thanks in advance.

    Hi, I have the same problem.
    I have WRP400 (firmware 2.00.32 - I try all firmware).
    Now my connection is 100/10 Mbit/s. 
    Directly connecting the modem to the computer I get the maximum speed 100 Mbit/s download and 10 Mbit/s upload.
    By connecting the router I get up to speed 47Mbit/s download and 10 Mbit/s upload.
    www.speedtest.net/my-result/3969122353
    In the router settings (SETUP / ADVANCED SETTINS) when the change parameter "WAN Phy Flow Control" to 100 half, the results are the same. When I change to 100 full I get speed for 10.
    I thing the option 100FULL is not working. Only 100 HALF.

  • Onboard Lan - Speed - 10mbit only

    -------------------
    I replied with this same post a thread of another user which had the same problem, but rcvd no answer...
    Hi.
    My problem is that i want it to work at 100mbit, but i can only work at 10 now.
    I'm experiencing this:
    I poweroff the computer, When i turn it on the 100mbit light turns on, but:
    When any OS starts (win98, winxp, win2000) the 100mbit light dissapears and the
    10mbit keeps turned.
    I tested this trouble with clean installs of windows 98, windows xp, windows 2000
    and i experienced the same in all these.
    The lan cable is the best quality, category 5, built & tested with proffessional tools.
    The switch is a dlink 10/100, etc. etc.
    I send u the details of my motherboard, drivers & versions
    Mother kt2 Combo VIA kt 266A

  • Time Capsule with an Airport Extreme bridge resulted in slow LAN speeds

    Wondering if other people are seeing this. I am unsure if this was a result of upgrading both my TC and AEx to 7.6, but my LAN speeds had suffered in this configuration.
    1.  Comcast cable modem connected to the WAN port on my TC.
    2.  Connected an ethernet cat6 cable from the TC to my Airport Extreme, which was configured as a bridge.
    3.  My desktop was connected to the Airport Extreme.
    4.  When doing file transfers within the LAN or general internet usuage, my network speeds were extremely low.
    5.  Disconnected the cat6 cable from the TC and plugged that directly to my desktop.
    6.  Network speed jumps up by a factor of 5. LAN file transfers and internet usuage has returned to what I had expected.
    Is there a known issue where a bridged AEx conncted to another Airport "main" device will result in all machines connected via the AEx to have slow LAN speeds?
    I didn't see this issue months ago. I did less than 2 months ago upgrade our machines to the 7.6 firmware, but after experiencing some hiccups on the network, reverted back to 7.5.2.  However, the slow LAN speeds haven't gone away when the two airport machines are connected to each other.
    Any insight or advise is appreciated.

    By now, millions of users have updated to 7.6 and I cannot recall seeing a post similar to yours on this forum.
    As far as a "known issue", you would need to contact Apple regarding that.
    Suggest that you have the AirPort checked out at an Apple store if you have one near you.

  • Fan speed problem Power Mac G5 Dual 1.8 GHz PowerPC - please help

    Please HELP, I have a fan speed problem with my Power Mac G5 Dual 1.8 GHz PowerPC
    This is a NOT an Intel machine. I am running Mac OS X v10.5.8
    Power Mac G5 - PowerMac 7,2 - Power PC 970 (2.2) - 1.8 GHz with 2 CPUs - L2 Cache (per CPU) 512 KB - Memory 8 GB - Bus Speed 900 MHz - Boot ROM version 5.1.5b1
    I have included below Links to download a sound file (.m4a) that I recorded of the fan speed problem and both a .pdf and .spx files of my system profile.
    download sound file
    http://homepage.mac.com/rep3/filechute/myG5dualsFans.m4a
    down load .spx file of my system preferences
    http://homepage.mac.com/rep3/filechute/systemProfileREP3-G5dual.spx
    down load .pdf file of my system preferences
    http://homepage.mac.com/rep3/filechute/systemProfileREP3-G5dual.pdf
    When did the fan problem start?
    After I replaced the mother board on the computer.
    Why did I replace the mother board?
    Because the experts at apple agreed with my diagnosis that the major crash problems & kernel panics must have some thing to do with a logic board gone bad. They would not work on it, because this Power Mac G5 dual 1.8 GHz machine is now a legacy model.
    What I have done to attempt to fix my fan speed problem? yes I checked the obvious things, here is a list:
    1) yes I checked to be sure that the new mother board was the same part number as the original one, and that all things that were unplugged from the old mother board - were actually plugged into the new mother board.
    2) all the fans work, I can see them spinning if I use a flashlight and look at them (cover on and off to get at some of them)
    3) check all RAM to make sure: a) it was installed properly b) that the RAM worked using TechTool Pro c) even started the machine with only the original RAM that came with it.
    4) I installed a Temperature monitor - to see if there was something reading as very hot inside that was causing the machine to continually run the fans at a high speed. No, no heat issues that I can see. Here are the reading from the sensors in degrees fahrenheit, 2009-10-11 16:11:01 -0500
    CPU A Die Temperature: 75.7℉

    5) zapped the PRAM
    6) followed the SMU reset instructions for
    Power Mac G5 (Late 2004)
    To reset the SMU on a Power Mac G5 (Late 2004) computer, simply do the following:
    • Turn off the computer by selecting Shut Down from the Apple menu or by holding the power button until the computer turns off.
    • Remove the power cord from the computer.
    • Wait two minutes.
    • Plug in the power cord.
    • Turn on the computer.
    7) followed the SMU reset instructions:
    Resetting the Cuda/PMU
    How to reset the PMU:
    • If the computer is on, turn it off.
    • Disconnect ALL cables from the computer, including peripherals and power.
    • If possible, move the computer to a place where you are not standing on carpet.
    • Open the case and ground yourself by touching part of the metal frame inside the computer.
    • Find the Cuda or PMU button
    • Press the Cuda or PMU button ONCE. Do not press the button more than once before starting the computer up again.
    • Wait 10 seconds, then reconnect the cables you removed in step 2 and turn the computer on.
    • If the computer still does not respond after resetting the PMU, the computer may require service from an Apple Authorized Service Provider.
    8) ran disk utilities, repaired permissions
    9) found a setting in the system preferences that a chat room person suggested had something to do with fan speed. In Energy Saver, under options, processor performance was set to highest, I set it to automatic - this did not change anything that I could tell - BTW I checked my other G5 (a single processor that works fine) that is the setting that that it is set to, and it is nice and quiet.
    10) restarted the machine, ..
    11) found a Fan Control System Update - but it did not install when I tryed to install it -
    12) booted from OSX install disk and ran that disk utility
    13) used OnyX to fix disk permissions, clear caches and temp items
    Nope - still have the same high speed fan problem. ... PLEASE HELP!!
    I have been reading in the MacInTouch reader reports - found this: some one said to use this - thermal re-calibration using the Apple Authorized Service Providers' disk - but that's not available, at least I can not find it - anyone? have an answer to finding this - or can do it for me? I am in Chicago.

    The Genius at the downtown apple store said that because it's a "legacy machine" they would not work on it, .. so should I push them?
    Well, I personally think that's ridiculous, I'd Push them, I'd call AppleCare & talk up the chain if need be... there the ones that have or should have that Disc... man o man... Personally I'll never visit an Apple Store again in my lifetime, maybe try an independent AASP if none of that helps!..

  • Athalon XP clock speed problem

    I hav just installed a K7N2 Delta Mobo in my system, but I'm having CPU clock speed problems.
    The Bios and the Infoview program both state that the CPU clock is running at 1105 Mhz. I am sure this should be 1533 Mhz for an 1800xp.
    I updated the bios using MSI live update, and the first time I booted the system, the bios displayed the speed as 1533 Mhz, but on every subsequent boot up it is back down to 1105 Mhz again.
    How can I get my processor to run at the correct speed?
    Thanks

  • K9N2 Sli Platinum + SSD OCZ Vertex 3 = Slow Speed Problem [PARTIALLY SOLVED]

    Hey folks,
    I have a problem with my new SSD. I only get sequential reads of 140MB/s and writes of 114MB/s.
    I think it is a driver related issue. I once got faster SATA2-like speeds but cannot reproduce the system settings again... Everything back to SATA1-like speeds after reboot.
    First my pc specs:
    MSI K9N2 Sli Platinum, BIOS v3.9
    - 6 SATAII ports by nForce 750a SLI
    - 2 ESATA (External-SATA) ports (back panel) by JMB363
    - Supports storage and data transfers at up to 3 Gb/s
    AMD Phenom II 965 Black
    Patriot PV224G8500ELKB Viper II Series DDR2 4GB (2 x 2GB, CL5 PC-8500/1066MHz)
    SSD SATAIII OCZ Vertex 3, 120GB, FW v2.11
    LG Internal BlueRay BH10LS30
    Windows 7 Ultimate x64
    I only get very slow speeds with the SSD. I tried so many things that I am getting very frustrated now, I am even thinking about getting a new board and ram just to get the SSD up to speed...  
    1)
    I installed Win7 first with all the default settings in Windows Setup from DVD. Default "IDE ATA/ATAPI controllers" driver was "Standard AHCI1.0 Serial ATA Controller".
    SSD was connected to SATA1-port,  On-Chip Sata Controller AHCI enabled in BIOS,  Extra RAID/IDE Controller disabled.
    All fine, but whichever benchmark I used (AS SSD, HD Tune Pro, Atto Disk Benchmark, CrystalDiskMark; other tools used: DriveControllerInfo, AIDA64/Everest, CrystalDiskInfo ) I got e.g. 140MB/s Read and 114MB/s Write sequentially (CrystalDiskmark, similar with random data AND only zeros ).
    Trim working (it seems) with AHCI driver. I also changed to nvstor64 driver (nforce driver setup 15.56), with is marginally faster but not what you would expect from a SATAIII drive on SATAII controller.
    2)
    I installed Win7 using "diskpart" (Shift-F10) during disk setup, setting a cluster size of 64k instead of default. No real change.
    3)
    After reinstall of Win7 x64 (again...), I changed from SATA1 port to SATA6 port, also enabled Extra Raid/IDE controller set to AHCI as well.
    Nothing changed. With all settings to default in Windows (ahci default driver), I then manually updated the ahci to nvstore64 driver in Device Management, rebooted.
    Then a minute later after reboot I got the following Sequential speeds with CrystalDiskMark:
    273MB/s read and 137MB/s write (random data)  +  274MB/s read and 220MB/s write (with zeros) !!!
    While I ran this benchmark Windows came up with a message: "You must restart your computer to apply these changes - Restart Now/Restart Later".
    After the previos reboot, when I changed manually from AHCI to NVSTORE, I had changed nothing in the current session, apart from running CrystalDiskMark.
    I did reboot and I was back to the slow SSD speeds again = 140/114 MB/s...
    4)
    I have tried every possible combination of mainboard SATA ports, drivers changing with nvidia setup/manually, deleting and disabling controllers (incl BSOD and startup repair :D ), chaning bios settings around, but I just cannot get back the faster speeds  
    There is never any change in speed, whether I use ahci or nvstore64, whichever benchmark I use, whether random or zeros...
    5)
    Could the SSD be broken, something internally preventing it from faster speeds (with this one random exception)?
    Could it be that my K9N2 SataPorts only allows for / reduced to SATA1 speeds?
    Am I missing something with the driver setup?
    Do I need additional drivers for the extra JMicron Controller when using SataPorts 5/6 ?
    I have no other mainboard to test this with...
    Please guys, I am going to jump out of the window if I can't fix it... :(
    Thanks, Mike

    Hey guys - problem 'solved':  
    I tested the OCZ SSD Vertex 3 120GB with following sata3 controller card http://www.lycom.com.tw/PE-115H.htm.
    The card itself works immediately (needs at least PCIe x4 slot, will work slower otherwise but still faster than the OCZ SSD @sata1 with nvidia chipset).
    There is some raid setup, doesn't apply to me, the boot even with the card is really only a few seconds longer and not annoying at all. Windows (7 x64) needed a driver, supplied on CD (which is cheap and making noise like h**l). The card works w/o the driver but doesn't harm to install it...
    Also, just to clarify, this sata controller card did not need any specific setup at all. Just put it in, plug in sata cable (I use akasa sata3-rated), maybe change boot device in BIOS (I didn't even have to), done - booting Windows as usual.
    Benchmark CDM with sata controller card Lycom PE-115H:

    http://img850.imageshack.us/img850/7549/cdmpe115hahcirand.png
    Speed is much better than before with nvidia chipset 750a SLI controller: sata1 (sata2 whenever it randomly worked):

    http://img13.imageshack.us/img13/6258/cdmahci0x0sata6contnv64.png
    Final thoughts:
    Well, I am happy with the SSD speed now (PCIe limited to 5Gbps). However, I had to spent quite some time to get it working on my sata2-cabable mainboard. Finally, I had to buy a extra controller card to get it working reliably at speeds faster than sata1. There is hardly any useful information on why this problem occurs with (older) nvidia chipsets and OCZ (sata3) SSDs. I still think that OCZ must know about this problem, but regards this issue as low priority, while at the same time not planning on giving up on sales to people with nvidia chipsets. Maybe OCZ should just make a big sticker on the box the drives come in with something like "Does/Might not work with nvidia chipsets, please use third-party sata controller card or different SSD manufacturer".   But then none of these potential customers would buy OCZ SSDs...  
    I will keep the sata3 controller, anyway handy to have, but return the OCZ Vertex 3 120GB and replace it with a SSD from a different manufacturer (Corsair Force GT, Patriot and OWC are not that great to get around here). The benchmarks for most people will not achieve the maximum advertised OCZ speeds anyway, so why not go with a brand that allows for some plug'n'play with some customer support.
    Hope this post helps others like me with their nvidia chipset  + sata1 speed problem

  • Java Audio Metronome | Timing and Speed Problems

    Hi all,
    I’m starting to work on a music/metronome application in Java and I’m running into some problems with the timing and speed.
    For testing purposes I’m trying to play two sine wave tones at the same time at regular intervals, but instead they play in sync for a few beats and then slightly out of sync for a few beats and then back in sync again for a few beats.
    From researching good metronome programming, I found that Thread.sleep() is horrible for timing, so I completely avoided that and went with checking System.nanoTime() to determine when the sounds should play.
    I’m using AudioSystem’s SourceDataLine for my audio player and I’m using a thread for each tone that constantly polls System.nanoTime() in order to determine when the sound should play. I create a new SourceDataLine and delete the previous one each time a sound plays, because the volume fluctuates if I leave the line open and keep playing sounds on the same line. I create the player before polling nanoTime() so that the player is already created and all it has to do is play the sound when it is time.
    In theory this seemed like a good method for getting each sound to play on time, but it’s not working correctly.
    At the moment this is just a simple test in Java, but my goal is to create my app on mobile devices (Android, iOS, Windows Phone, etc)...however my current method isn’t even keeping perfect time on a PC, so I’m worried that certain mobile devices with limited resources will have even more timing problems. I will also be adding more sounds to it to create more complex rhythms, so it needs to be able to handle multiple sounds going simultaneously without sounds lagging.
    Another problem I’m having is that the max tempo is controlled by the length of the tone since the tones don’t overlap each other. I tried adding additional threads so that every tone that played would get its own thread...but that really screwed up the timing, so I took it out. I would like to have a way to overlap the previous sound to allow for much higher tempos.
    I posted this question on StackOverflow where I got one reply and my response back explains why I went this direction instead of preloading a larger buffer (which is what they recommended). In short, I did try the buffer method first, but I want to also update a “beat counter” visual display and there was no way to know when the hardware was actually playing the sounds from the buffer. I mentioned that on StackOverflow and I also asked a couple more questions regarding the buffer method, but I haven’t received any more responses.

    Any help getting these timing and speed issues straightened out would be greatly appreciated! Thanks.

  • Broadband Usage and speed problems.

    Hi.
    I have question about broadband usage.
    Its 11 days and bt website says I used more then 20GB!
    Its nearly 1.8 GB per day! I used Internet for browsing website and receive one email pre day, I download twice large amount (about 1-1,5GB) and nothing more!
    I just wonder what going on? I try monitor my usage day by day from 5 days ago and its worst and worst!!!
    I nothing download but my usage going very fast.
    Its looks like I will be download about 3 movies per day that means I will have now more then 30 movies! Its must be something wrong!
    I used before VM and my average Internet usage was about 15-20GB per Month with solid 10MB speed.
    Now my speed is **bleep** from 8mb to 1mb and sometimes less then 512kb!!! And usage is higher !!!
    How can I see details about my usage?
    And q2
    About speed - in my area BT Infinity will be available from 31.12.2010
    Its mean still BT have same works, it might be cause my slow broadband?
    And from 25.11 till now is same problem with broadband, in three days I must reset BT Hub because there is no Internet. On BT Hub anything looks fine, Is IP address etc... But is no Internet telephone and no Internet as well.
    I check by used ping bbc.co.uk

    Hi.
    I hope you don't mind me asking a few questions, this may help to determine why your usage is as high as you're seeing.
    Do you have more than one computer connected ? Do you use iPlayer, or watch lots of youtube stuff ? Do you have any games machines such as XBox connected to the Internet ?
    Are you uploading lots of things ? uploads count as well as downloads.
    Are you up to date with all security and anti-virus packages, and have you run any scans recently ? (sometimes viruses and trojans can cause a usage problem).
    Your inherent speed problem could be due to various reasons, for example worsening line conditions due to weather and general wear and tear. Strangely viruses can cause a noticeable slow down, but mainly due to the computer being infected rather than the line being slow.
    Can you posssibly post the hub stats ?
    If you're using a PC, download something like Networx usage monitor and see if that can help. Of course it needs to be on each PC, but can't see the usage of games machines or Internet TV (or iPhone use etc).
    I used only 2 machines. Desktop PC and laptop. Laptop very light, just 1-2 hours per day only websurfing (3-5 websites with no movie or high quality images, 90% is just plain text)
    I not download lots of stuff, Like I just say, in VM my average monthly usage was 15-20 GB and I download few movie and lots of music.
    In December I just download one movie other traffic is just webserfing email.
    Youtube - yes I watch, but its not new staff for me, like just say my usage is not deferent then was in VM!
    Now usage monitor on BT web site say I used more then 20GB! in 11 days!!! if one movie will be 0.7GB its means I download about 30 movies!
    Its massive! I never download 30 movies in 2-3 months )
    This start about 5 days ago, when my strip goes to orange. My average Internet usage is 1.8GB !!! Even I for 2 days used Internet very little.
    I nothing upload.
    It is not possible, to anny worm or viruses used so big bandusuage if any software used Internet connection in background (like systems) its just kilobits not gigabits!
    If I will be use very hardly Internet I will be no rise alarm. But I now what I used. I have Internet for more then 7 years and now how far I go.
    And now is very strange - I less used inherent I have more GB used!
    In my calculation if my average usage per day will be 1.8GB I will used 55GB!!! I never used more 20 - max 30GB! It must be something wrong on BT site.
    I get BT Broadband option 2 be cause, I now I used about 15-20GB per months and BT Broadband option 1 is not for me, but 20GB in 11 days!
    We not talk abut 100MB! or 500MB per day we talk about nearly 2GB per day! Its massive!
    Is any chance to get detail Internet usage?
    Q2
    I loose Internet connection 3 times per week, so I need push reset button on hub.
    I left once Hub with no reset but in 5 hours it will still no Internet.
    Its looking very strange, because anything looks OK except I loos Internet phone (no blue telephone light)
    In hub stats is IP, is Downstream etc... but when I ping bbc.co.uk it say: host unavailable or similar.
    After reset working well. My be my Hub is faulty?

  • Another 3G Data speed problem on 4.1

    Hi All,
    Background info first:
    Using Win 7 Ultimate, iPhone 3gs 16gb, iTunes 10.0.0.68
    Located in Milton, Ontario, Canada (near Toronto), Rogers Cell network
    While my iPhone was on os 4.0, everything worked perfectly, I was getting 5 bars of service almost anywhere I was, and the 3g data was almost always fast (about 99% of the time it worked without an issue). On rare occasions my signal strength would dip to 4 bars, but that was the worst of it.
    I then upgraded to ios 4.0.2, and things have been downhill from there. My 3g speeds are generally terrible now, I usually get 1 or 2 bars, occasionally I will get 3 bars, and only once have I seen 4 bars. Needless to say, I can't really get online with much reliability anymore.
    I then noticed an update and upgraded to 4.1, things are even worse now. My geocaching app refuses to connect to the gps, it just hangs, and I am frequently missing phone calls (phone doesn't even ring, I just get a text telling me I missed a call). Battery life is all over the map now as well, some nights I will go to bed with battery at 100%, and when I get up it is at 88%, other times it has completely drained.
    I contacted Apple, they told me about the problem where the signal strength wasn't being reported properly, and now I am just seeing what my true signal strength is. I don't buy that at all, because if that is the case, then if my phone was showing 5 bars, and I was actually only getting 2 bars, I was still able to get really fast speeds, now that it is "correctly" showing 2 bars, I am getting terrible reception. Apple support suggested I contact an apple store and book an appointment.
    Went to apple store, met with the genius bar guy, he was really helpful, he thought it might be my sim card, so he gave me a new sim card, and then he decided he might as well give me a new phone in case it was the device, new phone came with os 4.0.2, so the only thing that really fixed was the geocaching app, but to get all of my contacts back, I had to restore from a backup, and I am back at 4.1, and no data speed.
    I contacted my cell carrier, and they can't figure it out either (one of the reps even told me to jailbreak my phone so I could downgrade to an earlier os).
    My mother in law has an ipad, on the same carrier, and she lives way out in the middle of the countryside. She gets 5 bars at her house, I get no service.
    Just wondering what people think is the issue, is it phone + os, or is it network?
    My thought is that it is the new os, my wife has the same phone with os 4.0, but on a different carrier, and she always gets 5 bars of strength.
    Thanks
    Mike

    Hi mlethbridge
    to clarify, I am not interested in jailbreaking the phone at all, I was just shocked that a customer service rep actually suggested I do that.
    Yes you have to wonder sometimes
    When I first contacted apple customer support, they told me to try restoring from a backup, did that but no change, then I restored to a new state, but I was still getting the 3g speed problems.
    When I received the new phone from apple, I did check the data speed, and it was still slow.
    So was it just slow or so slow that it was timing out before it would load anything?
    The geocaching app problem has been solved, I don't know why, but when I checked in Location Services, geocaching was turned off, that was a real simple fix (boy I feel like an idiot on that one), but that obviously didn't help the 3g speed.
    Yes, I wish sometimes all things were that easy to fix.
    As for the contacts, I always just kept them on my phone, count that as a lesson learned, they have all been synced over to my computer now.
    Good to hear, I would hate to see a post saying 'all contacts lost how do I get them back?'
    I personally treat my phone a portable storage device and never have anything on it that I cannot afford to loose.
    The point I was making with the iPad comparison is that my mother in law and I should be getting almost identical speeds (I am aware that the antenna might be a bit different in the iPad, but it shouldn't make that much of a difference), so I am not sure if it is just the way my cell network interacts with the new firmware, or if it is just the new firmware itself (if that makes sense?)
    I know what you mean, I'm not sure of the specs of the ipad v 3GS, but yes I would expect them to be reasonably similar.
    I did a bit more testing today, and went for quite a drive out to my brothers, the closest cell tower to him is about 5kms away (from my house it is about 1 km), and I was actually getting 4 and 5 bars out there, and the data speed was pretty good (not as good as I was used to, but it was a speed I could live with), but back at my house, I am getting only 1 bar again.
    On the surface of things, it sounds like its working as it should, all be it a bit slow maybe.
    I am really waffling as to which is at fault, is it the firmware or my cell network.
    I was recently discussing a roughly similar issue with another user where his connection on 3G was timing out Unfortunately we could not determine if it was firmware or carrier in the end, his problem just evaporated and his data just suddenly came good, which was great for him, but a bit frustrating for everyone as the cause was never found.
    In that case everything was attempted. You can read about here http://discussions.apple.com/thread.jspa?threadID=2570292 if you are interested.
    Try a few things;
    Make sure that you have the latest carrier setting file. It is possible that with the new 4.1 firmware, this file also requires updating. I know my carrier updated their's (Telstra Australia) after the upgrade.
    This should be an automatic thing, but it doesn't hurt to check. Connect your phone to iTunes and check for updates. If there is a carrier update available you will prompted to download it. Alternately, in the iphone go to Settings > General > About and if there is an update available, you will be prompted to downloading.
    I think that you want to determine is just what speed are you getting.
    My first step would to download a speed checker app, I use Speedtest.net app, but any free tester will do and use it to test your download and upload speeds. Compare this with different locations within your house and also where you are showing a much stronger signal. You will probably find that it varies a bit depending on your location.
    See if you can compare it with another iphone on the same firmware, same network, same location, or compare it with the ipad, but I think it would be better with another iphone.
    What happens if you turn off 3G and access only by Edge, speeds will drop because Edge is slower, but by how much? And WIFI, what is data like on it?
    What happens if you restore to 'new' and just sync the speed tester app. Does that resolve anything? This will determine if something else in the background is causing the issue.
    On that though, what other apps do you have running at the same time that could cause a slowdown? Mail? Facebook? Streaming Music? If multiple apps are running that require internet connection and then you open Safari to browse all the apps share the connection speed between them, so it could appear that the internet connection is slow.
    Hope this helps a little
